Oh, that's a pretty neat design with the offsets in the rear axle to simulate the movement of a horse. This is a new one on me. I know Garton Toy Co. used artillary wheels on a lot of their riding toy products, and there were other companies that used them, too. Hard to tell who the mfr. might have been. At least this is one horse tricycle that isn't a decorative repop!
